The countries that grow the most illegal Opium are Pakistan, Burma, Thailand, and Afghanistan, which is also the worldâs top supplier of Opium. Opium can also be grown in places like Mexico and Columbia. Afghanistan accounts to over 90% of the worldâs grown Opium.
This equation, I = V / R, tells us that the current, I, flowing through a circuit is directly proportional to the voltage, V, and inversely proportional to the resistance, R. In other words, if we increase the voltage, then the current will increase.
OhmÂ´s Law. There is a relationship between Voltage, Current and Resistance. The current in a circuit (amp) is directly proportional to the applied potential difference (volts) and inversely proportional to the resistance of the circuit (resistance). I = v/r. Example: I = v/r A nine volt battery supplies power to a bulb with a resistance of 18 ohms.
